University of North Carolina at Chapel Hill

What you'll study

The PhD programme combines advanced coursework, qualifying examinations and original research. Students pursuing optics and quantum chemistry typically study topics in quantum mechanics for chemists, electronic structure theory, molecular spectroscopy, nonlinear and ultrafast optics, quantum optics and photonics, and statistical mechanics. Training emphasises both theoretical tools (ab initio and many-body methods, quantum dynamics, open quantum systems) and experimental techniques (laser spectroscopy, single-molecule/ single-photon measurements, ultrafast methods and optical instrumentation).

Programme structure normally includes a period of formal coursework and seminars to build breadth and depth, rotations or short-term projects with different research groups, a written and/or oral qualifying examination to confirm readiness for independent research, and a sustained dissertation project under the supervision of departmental faculty. Students are encouraged to pursue interdisciplinary collaborations with neighbouring departments such as Physics, Applied Physics, Electrical and Computer Engineering, and materials science, and to use shared instrumentation facilities for microscopy, spectroscopy and device fabrication.

• Typical advanced modules: Quantum Chemistry and Electronic Structure Methods; Molecular and Optical Spectroscopy; Ultrafast Laser Techniques; Quantum Optics and Photonics; Statistical Mechanics and Dynamics; Computational Chemistry Methods.
• Research training: proposal writing, responsible conduct of research, teaching or mentoring experience, and presentation skills at internal and external meetings.

Entry requirements

Applicants are normally expected to hold a bachelor’s degree in chemistry, physics, materials science or a closely related discipline; many successful applicants hold a master’s degree or have equivalent research experience. Strong preparation in quantum mechanics, thermodynamics/statistical mechanics and physical chemistry or condensed-matter physics is important. Candidates should demonstrate quantitative and computational skills where relevant to their proposed research.

• Academic transcripts showing strong performance in relevant coursework.
• Research experience and a statement of purpose describing research interests in optics and quantum chemistry.
• Letters of recommendation, typically three, from academic or research supervisors who can assess research potential.
• For international applicants, proof of English language proficiency as required by the university.

Standardised tests are not universally required; applicants should check the department’s admissions page for current testing policies. Funding is commonly offered through research assistantships, teaching assistantships or fellowships for admitted doctoral students.

Career prospects

Graduates with a PhD focusing on optics and quantum chemistry pursue diverse careers. Many continue in academic research and teaching as postdoctoral researchers and faculty members. Others move into R&D roles in industry—photonics, quantum technologies, telecommunications, semiconductor and materials companies—or take positions at national laboratories focusing on quantum devices, ultrafast spectroscopy or optical sensing.

• Industry research and development in quantum computing, photonics, lasers and sensors.
• National laboratory scientist roles in spectroscopy, quantum materials and instrumentation development.
• Patent science, technical consulting, scientific software and engineering roles that leverage computational and experimental skills.
• Entrepreneurship and start-ups focused on optical technologies, quantum devices or advanced materials.
